I would not bring it up again. She heard you already. Be ready if she offers but do not expect it. Be supportive, understanding, validating, and mostly just hush when she talks about it upon her return. I just cannot imagine you getting an invite.
Words of affirmation are important and need to be spoken despite the fact you think she knows what you are thinking. So, you need to tell her things like she is a good mother, etc...periodically, it will make her feel loved. Don't bombard her just mention it occasionally when appropriate. Think about it. Don't you wish you were told you did a good job when it was simply expected and no one said anything to let you know they noticed? It shows love.
